Header Spec’s:
This header is available in 1 ¾”, 1 7/8”, 2”, 2 1/8” or 2 ¼” primary sizes.
Or we can build it as a step header in any combination you need.
Collectors can be 3”, 3 ½” or 4” depending on primary size, also, collector mufflers in up to 5” diameter.
This header has the 2 center tubes on each side going around the frame, so it is intended for drag type skinny front tires. May fit up to a 7” tire depending on wheel offset.
This header has good room for aftermarket A arms.

The engine must stay in the stock position either on solid side motor mounts or motor plates. Side mounts are Moroso #62630 frame mounts and Moroso #62515 engine mounts.
This header requires a Power Master #9540 or #9500 Nippondenso type starter, or #9526 for staggered mount. A stock starter or Hitachi type starter will not fit.

Measuring from the side of a stock oil pan we have 3 ¼” of room on the passenger side and 4 ¾” of room on the driver side for sump kick outs.
Spark plugs have good room, there is more room with angled spark plugs.
Oil filter has good access. With some kick out pans you may have to slide filter forward to get past sump.

This header will fit a power brake booster and clutch linkage, but will not fit a factory air conditioning box on the firewall or column shifter linkage.

Thank you,
